[−][src]Struct futures::sink::WithFlatMap
Sink for the Sink::with_flat_map
combinator, chaining a computation that returns an iterator
to run prior to pushing a value into the underlying sink
Methods
impl<S, U, F, St> WithFlatMap<S, U, F, St> where
S: Sink,
F: FnMut(U) -> St,
St: Stream<Item = S::SinkItem, Error = S::SinkError>,
[src]
S: Sink,
F: FnMut(U) -> St,
St: Stream<Item = S::SinkItem, Error = S::SinkError>,
pub fn get_ref(&self) -> &S
[src]
Get a shared reference to the inner sink.
pub fn get_mut(&mut self) -> &mut S
[src]
Get a mutable reference to the inner sink.
pub fn into_inner(self) -> S
[src]
Consumes this combinator, returning the underlying sink.
Note that this may discard intermediate state of this combinator, so care should be taken to avoid losing resources when this is called.
